Tag type mismatch: Module 1,01,02 Block 1001 (FC FC 31) is tagged TAGNAME in DB3.DBF with mismatching type ANALOG
This tag is for a block whose function code implies a different tag type than the one specified. For example, an analog type might be specified for a digital block. Some types of mismatches may not be problems, but others are and the tag will not work for the operator.
Example:
--Generating index: Module 1,01,17 Block Index Tag type mismatch: (FC 45) is tagged by tag LI45163 with mismatching type Analog.
These tags are in use, but are misdefined. They cannot be used on graphics, alarms or trends.
The snippet from the CLD/CAD sheet source shows that the block is a digital block but the tag definition says it is an ANALOG tag, which is why there is a note about a mismatch.
If an operator tries to make changes on a tag that is defined with the wrong type, those changes will not work.
